Has anyone else experienced what feels like bone on bone grinding when trying to bring hips in line with knees while performing frog poses? It goes away when I let up (rise higher vertically), but then so does the stretch... Anterior pelvic tilt seems to lessen the sensation, but I'm wondering whether I'm running into an arthrometric barrier. Right now, it feels like this pose is a dead end. I'm either in bone grinding pain or not feeling anything. Or my technique is way off. I'll try to remember to film myself in this position in the near future. Can any of you kind souls shed some light on this? Or perhaps recommend a variation to perform until my hips unlock more?
Another thing to note is that when doing Diamond Frog, I can get everything to the floor. I don't feel any sort of stretch tension in the muscles around my groin or inner thigh, but I do feel a slight "pulling apart" sensation inside the joint, almost as if I'm stretching ligaments -- is this by design?
